Hibernate or sleep

Discussion in 'Windows Vista Performance' started by Harmon Koeltz, Sep 8, 2007.

  1. Hi
    Running a notebook with Vista Home Premium. Did a disk cleanup and
    noticed I had about 2gig of Hibernate files. I left them alone but don't
    really understand hibernate vs sleep and whether to keep or delete these
    files.
    Suggestions

    TIA

    Harmon,

    Hibernate saves your current system and turns off all power. Should be used
    in a notebook that will be on battery.
    Sleep does almost the same but keeps some items powered up so that it can
    detect keyboard/mouse activity and wake up.

    Waking up from sleep is very fast, waking up from hibernate is fast. Power
    saving in either mode is substantial, but it does use some in sleep mode.
    If you have your unpluged laptop in sleep mode and you leave it that way for
    a long time it will eventualy (a day or so maybe) runout of power. When that
    happens it MAY (depending on various power settings) try to hibernate and
    shut down. Sometime there is not enought power to sucessfully do that and
    data loss and possible file system problems may occure. When you power it
    back up you will likely receive a warning that it was not properly shutdown
    and it will test itself.

    I think you're confusing sleep (which is new in Vista) and standby. Sleep
    combines the features of standby and hibernate. When you go into sleep
    mode the hibernate file is updated and then the machine remains in standby.
    If it runs out of power while in sleep mode, when it is turned back on it
    acts as if it were returning from hibernate. This prevents the "data loss
    and possible file system problems" that might happen after running out of
    power while in traditional standby.
    Sleep is a significant improvement (one of the few notable enhancements
    in Vista).

  4. So if I leave things alone, will the hibernate file continue to grow in
    size? What if I use sleep mode?

    TIA

    I think what you describe is 'hybrid sleep' which I think is default enabled
    (at least on my machine) but can be turned off. It is a major improvement in
    power handling.

    Michael

    aside: OP asked if the hibernate file grows. No, it is overwritten.

    I think you are confusing hybrid sleep with sleep. :)

    No, I wouldn't use the Disk Cleanup tool to delete the hiberfil.sys file.
    That file remains fairly static in size, and if you use Disk Cleanup to
    delete it, hibernate will no longer be available on your notebook. Disk
    Cleanup, under the Description section for that entry, warns you as to what
    will happen. See:

    You're right. Hybrid sleep is usually enabled by default on machines
    purchased with Vista, but plain sleep is an improved version of standby.
    Thanks for the correction.

  10. Hello Harmon,
    The hibernation file will not grow in size, it will remain the same
    size(roughly the size of RAM in your system)
    When the machine hibernates, what is loaded in RAM is saved out to disk in
    the hiberfil.sys so the RAM in the machine is not required to be powered up
    saving battery life.
    Thanks,
    Darrell Gorter[MSFT]

    Sleep...
    ordinary sleep....
    hybrid sleep.....
    hibernate.....
    ?!?!?

    OK is there really a definition of each of these, and which one(s) is VISTA
    actually using

  12. Hello,
    This link should explain them:
    http://windowshelp.microsoft.com/Windows/en-US/Help/335c6a5d-0304-4af1-b135-
    6bf6c124dc111033.mspx#EOMAC

    Windows Vista can use any of them, all of them, or none of them.
    What is available on any one system is dependant on the hardware, hardware
    settings, the installed drivers, the installed software of the system
    Thanks,

    Michael, I know I'm a bit late on the discussion but if you can answer my
    question on sleep and hibernate on a PC, I would be grateful. If I try to
    close down using sleep, my machine starts up again straight away. When I use
    shutdown, the screen shows -going into sleep mode- and the system switches
    off. ie I have to push the button on the tower to switch it on again. Am I
    missing something? I have a horrible feeling that a lot of things have to be
    in agreement in various places on the computer programs.

    There are several things that restart the computer. Mouse movement (some
    wireless units seem to constantly chatter so system restarts almost at
    once). Keyboard, I have seen some reports that some wireless keyboards also
    keep waking the computer. System scheduled tasks, that should restart at
    consistent time of day. And internet cards, which should start up the
    computer soon but at random delays.

    Some software prevents the system from sleeping at all but I am not aware of
    software that restarts from sleep (if not scheduled by the system
    scheduler).

    As I am not sure the pattern of 'starts up straight away' my recommendations
    are a bit vague.

    Unplug the internet cable from your tower, try sleep mode. If that works
    then there are easy solutions.

    If you have wireless mouse/keyboard, see if you can borrow a wired unit to
    use and see if that works. Solutions here are a bit more difficult and I
    don't have wireless so someone else will have to assist.

    I thought that 'shutdown' showed a message about preparing to shutdown, a
    message that has 'sleep' in it seems wrong to me.
    Having shutdown, yes you have to push the button on the tower to get going
    again. Also from a shutdown you will need to go thru the whole startup
    programs delay and login again.

    I'm using a wireless mouse and I have also experienced that the laptop
    restarts and the screensaver doesn't start unless I disconnect the wireless
    mouse..I hope this helps you.

    My desktop computer only has sleep mode. When my computer goes into sleep,
    it doesn't wake up and I have to turn it off manually and turn it back on. I
    talked to a Dell tech support guy and he said it was a bug in the new Windows
    Vista program. He had me change my settings so my computer would not go into
    sleep automatically after a certain period of time. Is this something
    Microsoft is going to fix? I hate not being able to put my computer into
    sleep when I'm not using it.

    A few questions:
    Did you buy your computer with vista, Installed it clean, or upgraded?
    When you say "Only has sleep mode" do you mean that it will not hibernate,
    cannot hibernate, gives you an error message, or is not available on the
    start menu?
    What settings did Dell support tell you to change

    There are two updates from Microsoft that may help you:

    hope this helps.

    I cleanup the hiberfil.sys file and the hibernate mode is no more avzailable.
    Is it possible to restaure it?
    If it is, how?
